The quilt patch titled
     Subject: sh: mm: set VM_IOREMAP flag to the vmalloc area
has been removed from the -mm tree.  Its filename was
     sh-mm-set-vm_ioremap-flag-to-the-vmalloc-area.patch

This patch was dropped because an updated version will be merged

Subject: sh: mm: set VM_IOREMAP flag to the vmalloc area
Date: Fri, 13 Jan 2023 11:19:21 +0800

Currently, for vmalloc areas with flag VM_IOREMAP set, except of the
specific alignment clamping in __get_vm_area_node(), they will be

1) Shown as ioremap in /proc/vmallocinfo;
2) Ignored by /proc/kcore reading via vread()

So for the ioremap in __sq_remap() of sh, we should set VM_IOREMAP
in flag to make it handled correctly as above.
